Kleinfelder conducted Phase I and II environmental site assessments (ESAs) on a 7-acre auto dealership property with an 80-year history of development. The project required identification of soil and groundwater contamination from current and historical on-site and off-site sources, including hydrocarbons and heavy metals.
The County planned on developing the property as a courthouse annex to serve citizens in the local area. Development required remediation of contaminated media to ensure a safe environment for employees and the public. Coordination with the Texas Commission on Environmental Quality was required to demonstrate adequate assessment of affected areas of the site and to document successfully completion of the site remediation.
As part of its work, Kleinfelder developed a remediation plan for soil removal, which was incorporated into a Remediation Project Manual and used to solicit public bids; provided contractor oversight throughout the project; characterized soil prior to removal, which facilitated recycling of affected soil for use as road base expedited analysis when unexpected stained soil was encountered; negotiated the classification of wastewater collection structures with the TCEQ to minimize regulatory requirements; and submitted reports with complete documentation to the TCEQ.
Based on initial ESA work, one tract was excluded from the property transaction due to contamination. Despite encountering two unanticipated buried concrete slabs, remediation of the site was completed on schedule, enabling building construction to move forward. Upon completion and submittal of reports to the TCEQ, the site was approved for closure.
